Chris Weidman, the reigning UFC middleweight champion, will need to have surgery to repair a meniscus issue, his coach told Newsday.

Ray Longo said Weidman has been dealing with the knee injury for a while, and heard it pop out twice in the past two weeks.

Weidman was scheduled to face Lyoto Machida at the end of May, but the bout has been pushed back to July and UFC 175.

“I have no reservations about July 5,” Longo said. “We’re just looking at this like we’re just pushing the fight back, that’s all.”

Weidman (11-0) is coming off back-to-back finishes vs. Anderson Silva. Machida replaced Vitor Belfort after Belfort was removed due to the banning of TRT.

UFC president Dana White called losing Weidman “brutal” and said that UFC CEO Lorenzo Fertitta “told him to do (the surgery), just (to) get this thing out of the way.”
